【Abstract】 The present status of the development of Cu-Cr contact materials is reviewed in this paper.Thedisadvantages of the traditional processing techniques for these materials such as powder mixing and sintering and pressure infiltration are discussed.Based on the discussion,some possible improvement measures are proposed.and the characteristics and process for forming Cu-Cr contact materials by means of spray forming are introduced.The result shows that Cr particles in the material are further fined and uniformly dispersed in Cu matrix,which will improve the switching properties of the materials.更多还原
